## Usage Examples

### Simple Typst Document

```python
import requests
import base64

response = requests.post(
    "https://studio-intrinsic--typetex-compile-app.modal.run/public/compile/typst",
    json={
        "content": """
#set page(paper: "a4", margin: 2cm)
#set text(font: "New Computer Modern", size: 11pt)

= My Document

This is a paragraph with *bold* and _italic_ text.

== Section 1

- Item 1
- Item 2
- Item 3
""",
        "main_filename": "main.typ"
    }
)

result = response.json()
if result["success"]:
    pdf_bytes = base64.b64decode(result["pdf_base64"])
    with open("output.pdf", "wb") as f:
        f.write(pdf_bytes)
    print("PDF saved to output.pdf")
else:
    print(f"Compilation failed: {result['error']}")
```

### Simple LaTeX Document

```python
import requests
import base64

response = requests.post(
    "https://studio-intrinsic--typetex-compile-app.modal.run/public/compile/latex",
    json={
        "content": r"""
\documentclass[11pt]{article}
\usepackage[margin=1in]{geometry}
\usepackage{amsmath}

\title{My Document}
\author{Author Name}

\begin{document}
\maketitle

\section{Introduction}

This is a LaTeX document with math: $E = mc^2$

\end{document}
""",
        "main_filename": "main.tex"
    }
)

result = response.json()
if result["success"]:
    pdf_bytes = base64.b64decode(result["pdf_base64"])
    with open("output.pdf", "wb") as f:
        f.write(pdf_bytes)
else:
    print(f"Compilation failed: {result['error']}")
    if result.get("log_output"):
        print(f"Log: {result['log_output']}")
```

### Multi-File Project (Typst)

```python
import requests
import base64

response = requests.post(
    "https://studio-intrinsic--typetex-compile-app.modal.run/public/compile/typst",
    json={
        "content": """
#import "template.typ": *

#show: project.with(title: "My Report")

= Introduction

#include "chapter1.typ"
""",
        "main_filename": "main.typ",
        "auxiliary_files": {
            "template.typ": """
#let project(title: none, body) = {
  set page(paper: "a4")
  set text(font: "New Computer Modern")

  align(center)[
    #text(size: 24pt, weight: "bold")[#title]
  ]

  body
}
""",
            "chapter1.typ": """
== Chapter 1

This is the first chapter.
"""
        }
    }
)

result = response.json()
if result["success"]:
    pdf_bytes = base64.b64decode(result["pdf_base64"])
    with open("report.pdf", "wb") as f:
        f.write(pdf_bytes)
```

### Including Images

For binary files like images, base64-encode them:

```python
import requests
import base64

# Read and encode an image
with open("figure.png", "rb") as f:
    image_base64 = base64.b64encode(f.read()).decode("utf-8")

response = requests.post(
    "https://studio-intrinsic--typetex-compile-app.modal.run/public/compile/typst",
    json={
        "content": """
#set page(paper: "a4")

= Document with Image

#figure(
  image("figure.png", width: 80%),
  caption: [A sample figure]
)
""",
        "main_filename": "main.typ",
        "auxiliary_files": {
            "figure.png": image_base64
        }
    }
)
```

### Using curl

```bash
# Typst compilation
curl -X POST https://studio-intrinsic--typetex-compile-app.modal.run/public/compile/typst \
  -H "Content-Type: application/json" \
  -d '{
    "content": "#set page(paper: \"a4\")\n\n= Hello World\n\nThis is Typst.",
    "main_filename": "main.typ"
  }' | jq -r '.pdf_base64' | base64 -d > output.pdf

# LaTeX compilation
curl -X POST https://studio-intrinsic--typetex-compile-app.modal.run/public/compile/latex \
  -H "Content-Type: application/json" \
  -d '{
    "content": "\\documentclass{article}\n\\begin{document}\nHello World\n\\end{document}",
    "main_filename": "main.tex"
  }' | jq -r '.pdf_base64' | base64 -d > output.pdf
```

## Error Handling

When compilation fails, the response includes:
- `success: false`
- `error`: Human-readable error message
- `log_output` (LaTeX only): Full compilation log for debugging

Common errors:
- **Syntax errors**: Check your source code for typos
- **Missing files**: Ensure all imported/included files are in `auxiliary_files`
- **Package not found**: Most common packages are available; contact support for additions
- **Timeout**: Complex documents may timeout after 60 seconds

## Rate Limits

- No authentication required
- Please be respectful of shared resources
- For high-volume usage, contact support

## Tips for Agents

1. **Always check `success`** before accessing `pdf_base64`
2. **Parse errors** to provide helpful feedback to users
3. **Use minimal documents** when testing - complex documents take longer
4. **Cache results** if compiling the same content multiple times
5. **Include all dependencies** in `auxiliary_files` for multi-file projects
